This is almost twice as much trash per person as most other major countries. What happens to this trash? Some gets recycled (回收利用) or recovered and some is burned， but the majority is buried in landfills.How Much Trash Is Generated?Of the 210 million tons of trash， or solid waste， generated in the United States annually， about 56 million tons， or 27 percent， is either recycled (glass， paper products， plastic， metals) or composted (做成堆肥) (yard waste)。 The remaining trash， which is mostly unrecyclable， is discarded.How Is Trash Disposed of?The trash production in the United States has almost tripled since 1960.
